Observations: Hypericin, originating from Hypericum perforatum, is a potent photosensitizer known to induce skin phototoxicity when given systemically. Hypericum perforatum is a botanical extracts with anti-inflammatory and antibacterial effect. Photocontact dermatitis is a common cutaneous reaction by various herbs. We describe a 54-year-old female patient with Hypericum perforatum associated ...

OBJECTIVES To compare the efficacy and tolerability of Hypericum perforatum (St John's wort extract) with imipramine in patients with mild to moderate depression. DESIGN Randomised, multicentre, double blind, parallel group trial. SETTING 40 outpatient clinics in Germany. PARTICIPANTS 324 outpatients with mild to moderate depression. INTERVENTION 75 mg imipramine twice daily or 250 mg h...

OBJECTIVES Hypericum perforatum L. is a medicinal plant containing many polyphenolic compounds, ‎including flavonoids and phenolic acids with antidepressant and anti-inflammatory properties. ‎This study was investigated the effects of Hypericum perforatum extract (HPE) on immunity, ‎body weight (BW), and spleen index (SI) in rats.‎ MATERIALS AND METHODS A total of 24 Wistar male rats were ran...

AIM Effects of homeopathic treatment with Hypericum perforatum (Hypericum) on peripheral nerve regeneration was studied using a rat sciatic nerve transection model. METHODS Fifty-four male healthy White Wistar rats were divided into three experimental groups (n = 18), randomly: Sham-operation (Sham), control: silicon tube (Sil) and treatment: silicon tube + Hypericum (Sil/Hypericum). In the S...

Blowflies use discrete, ephemeral substrates for larval development. After exhaustion of the food supply, larvae will disperse in search of sites to burrow and pupate or will seek other sources of food in a process known as post-feeding larval dispersal. In this study, the effect of temperature was investigated as it is one of the most important aspects of the environmental variables in this pr...

Obesity is a chronic disease of multifactorial origin and currently is a serious public health problem. The treatment of morbid obesity can be effectively done by bariatric surgery. The present study aimed to evaluate the influence of changes in food intake on body composition and some hematologic and biochemical variables in the period of eight weeks after Roux-en-Y gastric bypass (RYGB). The ...

SCHMIDT-NIELSEN, K., E. C. CRAWFORD, JR., A. E. NEWSOME, K. S. RAWSON, AND H. T. HAMMEL. Metabolic rate of camels: effect of body temperature and dehydration. Am. J. Physiol. 2 I ~(2) : 341-346. 19670 -The effect on metabolic rate (oxygen consumption) of changes in body temperature and state of dehydration was studied in four camels. The data were subjected to multiple-regression analysis. The ...

This study demonstrates the changes in six different pathophysiological parameters such as body weight, body temperature, fecal pellet count, blood-brain barrier (BBB) permeability, plasma corticosterone level and emergence of hemorrhagic peptic ulcer spots due to exposure to high environmental heat in three different age groups of freely moving rats. Methods: Each age group of rats was sub di...

The effect of genotype-temperature interactions on body weight has been studied in a natural population of Drosophila melanogaster using four isogenic strains derived from it, and their hybrid F(1) and F(2) progenies. Measurements were made at four constant temperatures-25 degrees , 21 degrees , 17 degrees and 13 degrees C-and at a temperature oscillating between 17 degrees and 25 degrees C.-Lo...
